Solution Overview

Problem

Existing hair dye and other fluid composition applications require separate components to be mixed immediately before use, which can lead to uneven results, safety hazards, and the need for additional accessories, making them inconvenient and costly, especially for small applications.

Innovation Solution

A modular multi-chamber dispenser with pressure-activated gates and interchangeable applicators that integrates separated fluid components, allowing for mixing and application directly on a targeted surface without additional accessories, reducing the risk of mess and damage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separated fluid components are mixed immediately before use, then the chemical reaction efficacy is improved, but the risk of uneven application and safety hazards increases

Engineering Contradiction:

Improvechemical reaction efficacyVSAvoidsafety hazards and uneven application

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent combines the mixing chamber and application dispenser into a single integrated device. The separated fluid components are mixed within the dispenser body, and the mixed solution is immediately applied through the same device, eliminating the need for separate mixing bowls and reducing the risk of uneven application or spills.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces an intermediary mixing chamber that acts as a controlled transition zone between the separated component containers and the application point. This intermediary structure allows for controlled mixing under supervision, preventing direct uncontrolled mixing and reducing safety hazards.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If traditional mixing kits with multiple accessories are used, then the completeness of the mixing process is improved, but the device complexity and cost increase

Engineering Contradiction:

Improvecompleteness of mixing processVSAvoidnumber of accessories

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent designs a multi-functional dispenser that performs multiple operations: storing separated components, mixing them, and applying the mixed solution. This single device replaces traditional kits that require separate mixing bowls, measuring tools, applicators, and cleaning supplies, thereby reducing complexity while maintaining completeness.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent merges storage containers, mixing chamber, and application mechanism into one integrated system. The separated fluid components are stored in built-in containers, mixed in an integrated chamber, and applied through a unified dispenser, eliminating the need for multiple separate accessories.

Inventive Principle:

Principle #5Merging (Combining)

3Duration of action of stationary object

If mixed components are left to oxidize for too long, then the chemical reaction is completed, but unwanted results such as uneven color and chemical burns occur

Engineering Contradiction:

Improveoxidation timeVSAvoiduneven color and chemical burns

Core Design Contradiction:

Duration of action of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The patent prepares the mixed solution immediately before application within the dispenser. The mixing occurs just prior to use, and the solution is applied continuously without prolonged standing time, preventing over-oxidation and associated harmful effects while ensuring complete chemical reaction.

Inventive Principle:

Principle #10Preliminary action

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

AI summary

A modular and multi-chamber hair dye dispenser and kit including the same are provided. Namely, the dispenser comprises a first and second chamber configured to each hold a fluid substance and threadedly engage one another. A pressure activated gate is disposed between the chambers and configured to selectively permit fluids held therein to mix upon screwing the chambers into one another. A removable spacer may be disposed between the chambers to prevent breach of the gate until desired. An outlet secured within an open front end of the first chamber is configured to dispense mixed fluid via one or more openings and, as desired, receive an interchangeable applicator. In a kit, fluid substances may comprise hair coloring agent and a developer, activator, or oxidizer.
